Linux Superhero?

Learning Linux is a process. The OS offers stability and power; but as the uncle of Peter Parker (aka Spiderman) said, with great power comes great responsibility. If your organization doesn't support and encourage continuous learning, get off the Linux boat now--you're doomed to failure.

If you tinker with Linux in the lab, read and post to newsgroups or mailing lists, and even (gasp) load Linux on your home computer, your enterprise's transition to Linux should go smoothly. If not, get started in the lab and join some newsgroups (see "A Little Linux Netiquette,").

The lab is one of the primary sources of lifelong learning for your new platform. It helps you simplify your setups and understand how one subsystem affects another. Linux's command line is like a scalpel--it's crucial for delicate surgery, but if you're not experienced with it, you risk severing an artery. A single misplaced space character in a script or at the command line can wipe out your whole file system. The command rm -rf foo / is quite different from rm -rf foo/.

Meanwhile, you'll need to integrate your new Linux system with legacy non-Linux systems. Keep your support contracts for those legacy servers in place in the interim to prevent finger-pointing in case of downtime. It's all about experience.
